I don't want to pay another tax to the federal government. If my state implemented some sort of tiered tax plan based on mileage that worked in conjunction with my already annual registration and inspections, that'd be different.

That's my biggest issue with democrats is the assumption that all problems need national solutions when the states can handle things like this.

If I had to guess, this would be a simple readout of the odometer and not some intricate satellite-based tracking system.
